Electric Literature of 1001401-62-2, New Advances in Chemical Research in 2021. Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 1001401-62-2, name is 2-(2H-1,2,3-Triazol-2-yl)benzoic acid, molecular formula is C9H7N3O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
10818] To 2-(2H-1,2,3-triazol-2-yl)benzoic acid (125 g, 0.6 mmol) and DMF (4 mE) was added (i-Pr)2NEt (0.23 mE, 1.3 mmol) and HBTU (155 g, 0.6 mmol). Afier 10 mm, the title compound from step B (146 g, 0.4 mmol) was added. After stirring overnight at it, saturated NaHCO3 (aq.) was added and the mixture extracted with EtOAc (3x). The combined organics were dried (Mg504) and concentrated. Purification via preparative HPEC gave the title compound (89 mg, 47%) as a beige solid. MS (ESI) mass calcd. for C2QH18F3N70, 429.2; mlz found 430 [M+H]. 1H NMR (DMSO-D5): 8.47 (s, 0.3H), 8.24 (s, 0.7H), 8.14-8.05 (m, 2.2H), 8.02 (s, 0.7H), 7.85 (d, J=7.2 Hz, 1.3H), 7.72-7.55 (m, 1.7H), 7.49-7.34 (m, 1.4H), 7.13 (t, J=7.4 Hz, 0.7H), 4.58 (t, J4.3 Hz, 0.7H), 4.44 (d, J=4.7 Hz, 0.3H), 4.04-3.93 (m, 0.3H), 3.82 (t, J=4.1 Hz, 0.3H), 3.79-3.70 (m, 0.7H), 3.54 (d, J4.8 Hz, 0.7H), 2.07-1.90 (m, 1H), 1.85-1.07 (m, 5H).
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 2-(2H-1,2,3-Triazol-2-yl)benzoic acid, hurry up and to see.
